4. What is a Serial Killer?
What do YOU think the definition is?

5. Definitions of a Serial
Killer
Someone who murders 2 or more
victims with an emotional cooling
off period between the homicides

6. Profiling Beginnings
 UNSUB-unknown subject
 “If you want to understand the
artist you have to look at the
painting”
 What took place?
 Why did it happen the way it did?
 Who could have committed this
crime for these reasons?

7. Inside the Mind of a Killer
 They sense weakness and vulnerability
 Thrill of the hunt gets them going
 Behavior reflects personality
 “Homicidal triad”-cruelty to small
animals, fire-setting and bedwetting
beyond an appropriate age
 Three most common motives of serial
killers and rapists are DOMINATION,
MANIPULATION and CONTROL
 Serial killers are sexual predators

8. Inside the Mind…
 One of their main fantasy jobs is police
officer
 Many are “police buffs”-they hang out
at police bars and talk shop. They also
like to find out about the investigation
 Triggering event-”stressor”-most
common are losing job and losing
wife/girlfriend

9. Inside the Mind…
 Most single important factor in the
development of a serial killer is the role
of fantasy
 Many fantasize about a relationship
between sex and death (Ed Kemper,
Jeff Dahmer)
 Behavior escalates from fantasy to
reality, helped along by pornography
and cruelty to animals and peers.
Fantasy is in place long before murders
start

10. The Role of Fantasy
 82% of serial killers report daydreaming
in their childhood accompanied by
compulsive masturbation. If fantasies
are violent, violence and sex become
associated with one another
 71% report feeling isolated as children.
Isolation encourages substitution of
fantasy for human contact

11. The Role of Fantasy:
Test Runs
 Serial killers start out by giving the
fantasy a test run
 This involves cruelty to animals
and small children
 Stealing women’s underwear,
exhibitionism, voyeurism, burglary
and other minor offenses

12. Organized or
Disorganized?
Organized Disorganized
 Continual refinement  Bodily mutilation
of fantasy  Lack of preparation
 Improvement of  Body left in view
details from one  Violence is sudden
crime to the next
 Often they are
 Obsession with detail
severely disturbed
 Planning of crime  Some UNSUBS are
and disposal of body mixed
 Socially competent
 Follows crime in the
news

13. M.O. vs Signature
Modus Operandi Signature
 Learned behavior  What the UNSUB
does to fulfill
 What the UNSUB
himself
does to commit  Does not change
the crime
 Expresses the
(shooting,
UNSUB’s
stabbing) personality
 It can change  He NEEDS to do it

14. Deciphering Crime
Scenes
 Blitz style attack or attack on small or
physically challenged people means
attacker has little confidence and self-
esteem, not charming, asocial type
 Sexual attacks on the elderly mean the
person has little or no sexual experience

15. Deciphering Crime Scenes
 Severe facial trauma/covering the face
means the person may have known the
victim or is trying to depersonalize her
 Covering the entire body means the
person feels bad about what he did
 Multiple stab wounds mean a lot of
anger and emotion (think about 30 stab
wounds)

16. History of Serial Killing
 Serial killing may be a much older
phenomenon than we realize
 Stories about witches, werewolves,
vampires may have been created
to explain atrocities committed by
humans (Chikatilo)
